So, in addition to service and assistance dogs, which we know how people in multiple-multiple ways. We also have story dogs, and they're different. They are not service dogs. They're partnered with a working professional to improve the physical and emotional health of individuals who are under that professional’s care. So, if I have a facility dog and bringing it to our impatient psychiatry unit, I am bringing that dog to help those patients on that particular unit; and the dog has been trained to work on that particular unit. They respond to basic obedience and skilled task commands that are appropriate for that particular setting, and they compliment other therapies like therapeutic recreation and occupational therapy and psychotherapy. They're typically on that unit as long as I am, and so they're there every day. But they also would go home with that working professional and then they're off service, so to speak.
